" It is often supposed that, apart from their 'extraordinary powers of memory', expert players have phenomenal powers of calculation. The beginner believes that experts can calculate dozens of moves ahead and he will lose to them only because he cannot calculate ahead so far. Yet this is utter nonsense. From my own experience I can say that grandmasters do not do an inordinate amount of calculating. Tests (notably de Groot's experiments) supports me in this claim.
